The Best Foods for Better Brain Health

What you eat today can help shape how your brain functions for years to come.  

As life expectancy increases, many people are asking: how do we protect our brains and maintain high cognitive function as we age? We now have a much more in-depth understanding of how lifestyle and environmental factors impact our brains.  

Long-term studies have shown that nutrition is a powerful tool for better brain health throughout one’s lifetime. The MIND diet (Mediterranean-DASH Intervention for Neurodegenerative Delay), first described in research from 2015, was evaluated in a 10-year study that examined how dietary patterns relate to cognitive decline and dementia risk in older adults over time.  

This and other research show that certain foods contain nutrients that play an important role in supporting your brain. Here are a few you should know.  

Dark Leafy Greens and Lutein 

Greens like spinach, kale, collard greens, and broccoli are rich in lutein, an antioxidant that can cross the blood-brain barrier. It accumulates in brain regions involved in memory and cognition and may help reduce oxidative stress and inflammation. 

In MIND diet research, individuals who consumed at least one serving of leafy green vegetables per day had significantly slower rates of cognitive decline compared with those who consumed them less frequently. Even small, consistent amounts were associated with meaningful differences in long-term brain health. 

Berries and Brain Protection 

Berries are rich in polyphenols — particularly anthocyanins — compounds linked to improved neuronal signaling and reduced inflammation.   

The MIND diet recommends at least two servings of berries per week, and observational studies have shown that regular berry consumption may help slow cognitive decline and reduce your risk for Alzheimer’s disease. 

Fatty Seafood and DHA 

Fish like salmon, sardines, trout, and mackerel provide DHA, an omega-3 fat that’s a structural component of brain cells and helps support communication between neurons. DHA also plays a role in maintaining cell membrane integrity and reducing inflammation. 

Try to get at least one serving of fish per week; higher intake is associated with better cognitive performance and lower risk of dementia in long-term cohort studies. 

Nuts, Seeds, and Healthy Fats 

Nuts and seeds provide monounsaturated fats, vitamin E, and plant-based omega-3 fats, all of which support cardiovascular health and may help protect brain cells from oxidative damage. Vitamin E has been associated with slower cognitive decline in observational studies, due to its role as a fat-soluble antioxidant that helps protect brain cells from oxidative stress, inflammation, and other forms of damage. 

The MIND diet recommends five servings of nuts per week, recognizing their role in supporting vascular health, which is closely tied to cognitive health. 

Beans and Legumes 

Beans, lentils, and other legumes are rich in folate, fiber, magnesium, and plant-based protein. These nutrients support metabolic and cardiovascular health, help regulate blood sugar, and promote a healthy gut microbiome — all factors associated with lower risk of cognitive decline.  

Consume beans or legumes at least three to four times per week as part of a consistent, plant-forward eating pattern. 

Olive Oil as the Primary Fat 

Olive oil is recommended as the primary cooking and dressing fat in the MIND diet because of its high monounsaturated fat content and anti-inflammatory compounds.  

Regular use of olive oil in place of saturated fats has been associated with better cardiovascular health, which is a key contributor to long-term brain health. 

Foods to Limit 

In addition to emphasizing nutrient-rich foods, the MIND diet also identifies foods you should limit in your daily life. These include: 

• Red meat: fewer than four servings per week  

• Cheese: only occasionally  

• Fried foods and fast food: less than once per week  

• Butter and margarine: less than 1 tablespoon per day 

• Pastries and sweets: only occasionally  

These guidelines are grounded in strong evidence showing that diets high in saturated fats and highly processed foods can increase the risk of heart disease, metabolic issues, and declining brain health over time.

Although the initial aim of the MIND diet was to improve brain health, it may also help manage heart disease, diabetes, certain cancers, MS, and even mental health conditions like anxiety, depression, and ADHD.
